Procedure

To a solution of (S)-2-(4-chloro-8-oxo-9-(2,2,2-trifluoroethyl)-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl)acetic acid (50 mg, 0.133 mmol) in dichloromethane (25 mL) was added 1′H-spiro[piperidine-4,4′-quinazolin]-2′(3′H)-one (31 mg, 0.14 mmol) followed by 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (47 mg, 0.15 mmol) and triethylamine (1.0 mL). After 12 h, the reaction mixture was washed with aqueous NaHCO3 followed by 1.0 M HCl and dried (Na2SO4). The solvent was removed and the crude product was purified by flash chromatography using 7% MeOH in dichloromethane to give (S)-4-chloro-7-(2-oxo-2-(2′-oxo-2′,3′-dihydro-1′H-spiro[piperidine-4,4′-quinazoline]-1-yl)ethyl)-9-(2,2,2-trifluoroethyl)-6,7,9,10-tetrahydroazepino[3,4-e]indazol-8(3H)-one (61 mg, 79%) as awhite powder. MS (ESI) 575 (M+H); Rf=2.133.
